Sounds like what your friend is looking for is a copy stand set up to
photograph loose sheets. This might do.

http://www.instructables.com/id/Copy-Stand-Cheap-and-easy-to-build/

If necessary to photograph larger manuscripts, the design could be
easily made larger.

What happens next depends on whether your friend just needs images of
the pages or needs to extract the musical notation from the images.

Converting words or musical notation in the images is going to require
some kind of OCR (Optical Character Recognition) software. Most flatbed
scanners I know of come with an OCR application. I don't know if any of
them can interpret music notation.

You might also do a Google search for "rare document digitization
equipment".

Now you know as much about it as I do.

Re: question for the list from a friend

[Igor PDML-StR]

In that case, a hand-scanner would be a viable option.
But that's, in my mind, is a tedious job, especially if the volume is high 
("large number of pages", as you wrote).


But in that case, any type of designed-for-large-volume camera based setup 
that I can envision, would not be anywhat different from a scanner.

I would guess there are scanners that are somewhere in-between a
traditional flatbed scanner and a camera: you place the document face up, 
and the scanning element (plate with the scanning head) is mounted above 
it (so it is a non-contact scanner).


I'll stop my speculations here.

I don't know, perhaps the pages are not removable and you can't lay them 
flat?

Here you go.



If your friend is, say, Russian - you might want to get the inscription
in a different language.
